When a parameter is invalid for a given filter type, the parametric EQ commands will still set that parameter, however its value will not be used for filter computations. This valid/invalid parameter information above is provided mainly as guidelines for programmers writing control software for the Vortex. If a parameter is not valid for a specific filter type, then the control for editing that parameter should be disabled or removed when that filter type is selected.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example

Description

Status Message

Set the parametric EQ on input 1 , band 2 to the following parameters: type

=parametric filter, frequency

=1250 Hz, bandwidth = 40 1/100th octaves,

S01PEQIA1,2,1,1250,40,-20,1,1 gain = -20 dB, S01PEQIA1,2,1,1250,40,-20,1,1 enabled = yes,

slope = 1 dB per octave. The value of the slope parameter is irrelevant for this type of filter, we could have set it to anything.

This long-range connectivity is essential in large conference rooms and auditoriums where devices are often spread out over considerable distances. The serial connection is often more reliable than wireless options, which can be susceptible to interference.

Another notable characteristic is its versatile compatibility with a range of devices, including cameras, projectors, and interface panels. This allows users to control multiple devices from a single point, streamlining the operation of complex setups. The straightforward nature of RS-232 commands simplifies integration, which is a significant benefit for both installers and end-users.

Polycom RS-232 also supports various baud rates, giving users the flexibility to optimize communication speed based on their requirements. This adaptability ensures that users can achieve the desired performance, whether they are managing basic functions like power and volume control or more complex commands for switching video sources or adjusting settings.

The technology also features error-checking capabilities, which contribute to its reliability in communication. This reduces the likelihood of issues during operations, ensuring that commands are correctly received and executed. Additionally, its structured protocol aids in diagnosing and troubleshooting, making it easier to manage any issues that arise.

With its robust nature and proven reliability, Polycom RS-232 remains a pivotal technology in the realm of audiovisual communications. Its combination of long-range capabilities, compatibility, flexibility, and reliability makes it an essential tool for enhancing the efficiency of modern communication environments. As technology continues to evolve, the importance of dependable interfaces like Polycom RS-232 cannot be overstated, ensuring seamless integration and operation of sophisticated communication systems. Whether used in educational institutions, corporate environments, or event venues, Polycom RS-232 guarantees a streamlined experience in device management and control.
